When the Interference Check dialog opens, if you selected any elements in the view, the dialog is filtered to display only those element categories. If you did not select any elements, the dialog displays all categories from the current project.

On the left side of the dialog, select Current Project, then select the desired categories. In my example, we'll select Structural Framing as the category. On the right side of the dialog, select the second Categories from drop-down. (This value could be a current selection of elements, the current project, or a linked Revit model). Select the desired categories and OK to run the check.

If there are no interferences a dialog window informs you of this. If there are interferences to report, the Interference Report dialog displays. This dialog lists all elements that conflict with one another. Because we cannot set any tolerance in Revit we would need Navisworks Manage, which has more in-depth capabilities for carrying out Clash Detection.
